The poor oocyte quality in older women has previously been linked to the depletion of the ovarian reserve of primordial follicles and an increase in granulosal apoptosis. Granulosa cells were collected from 198 follicles and individually analysed by flow cytometry. In the young IVF patients, the level of apoptosis was inversely proportional to the expression of bone morphogenetic protein (BMPR1B) and follicle stimulating hormone (FSH) receptors. Conversely, in the older patients this relationship became dysregulated...

Cytochrome P450 enzymes are required for the synthesis of cholesterol and steroid hormones. Cytochrome P450 oxidoreductase (POR) donates electrons to microsomal cytochrome P450 enzymes. POR deficiency (PORD) is a rare autosomal recessive disease. In patients with PORD, steroid hormone synthesis is disrupted, which can cause infertility. The objective of this study was to report on a case of in vitro fertilization-frozen embryo transfer (IVF-FET) in a patient with PORD. The patient's hormone (i.e. 17α-hydroxyprogesterone) and electrolyte levels were within normal ranges ordinarily...

BACKGROUND: Patients undergoing in vitro fertilisation (IVF) receive various adjuvant therapies in order to enhance success rates, but the true benefit is actively debated. Growth hormone (GH) supplementation was assessed in poor-prognosis women undergoing fresh IVF transfer cycles. METHODS: Data were retrospectively analysed from 400 IVF cycles, where 161 women received GH and 239 did not. RESULTS: Clinical pregnancy, live birth rates and corresponding ORs and CIs were significantly greater with GH, despite patients being significantly older with lower ovarian reserve...

Most IVF-conceived children are healthy, but IVF has also been associated with adverse obstetric and perinatal outcomes as well as congenital anomalies. There is also literature suggesting an association between IVF and neurodevelopmental disorders as well as potentially long-term metabolic outcomes. The main driver for adverse outcomes is the higher risk of multiple gestations in IVF, but as the field moves toward single embryo transfer, the rate of multiple gestations is decreasing. Studies have shown that singleton IVF pregnancies still have a higher incidence of adverse outcomes compared to unassisted singleton pregnancies...

BACKGROUND: Human follicular fluid (HFF) provides a key environment for follicle development and oocyte maturation, and contributes to oocyte quality and in vitro fertilization (IVF) outcome. METHODS: To better understand folliculogenesis in the ovary, a proteomic strategy based on dual reverse phase high performance liquid chromatography (RP-HPLC) coupled to matrix-assisted laser desorption/ionization time-of-flight tandem mass spectrometry (LC-MALDI TOF/TOF MS) was used to investigate the protein profile of HFF from women undergoing successful IVF...

Data from in vitro and in vivo models suggest that malnutrition and stress trigger adaptive responses, leading to small for gestational age (SGA) blastocysts with fewer cell numbers. These stress responses are initially adaptive, but become maladaptive with increasing stress exposures. The common stress responses of the blastocyst-derived stem cells, pluripotent embryonic and multipotent placental trophoblast stem cells (ESCs and TSCs), are decreased growth and potency, and increased, imbalanced and irreversible differentiation...

Soluble receptor for advanced glycation end products (sRAGE) can decoy the toxic AGEs and is considered to be a protective factor. This study aimed to evaluate the correlation between intrafollicular sRAGE levels and clinical outcomes in infertile women of young or advanced maternal age (AMA) undergoing in vitro fertilization (IVF). A total of 62 young women and 62 AMA women who would undergo IVF were included in this prospective study. The intrafollicular sRAGE concentration was measured to determine its association with the number of retrieved oocytes, fertilized oocytes, high-quality embryos or achievement of clinical pregnancy in young and AMA women, respectively...

PURPOSE OF REVIEW: Growth hormone (GH) has been used as an adjunct in ovulation induction and IVF for 25 years, particularly as an adjunct to ovarian stimulation for women who had a previous poor response to stimulation in an IVF cycle. It does not have US Food and Drug Administration approval for this use. Unfortunately, due to the problems inherent with recruiting women who have undergone unsuccessful IVF treatment cycles and their inevitable low live birth rate per initiated cycle, many studies performed to date have been underpowered...

STUDY QUESTION: Does bisphenol-A (BPA) affect gene expression in human membrana granulosa cells (MGC)? SUMMARY ANSWER: In vitro, short exposure to supra-physiological concentrations of BPA alters human MGC gene expression. WHAT IS KNOWN ALREADY: Exposure to BPA may interfere with reproductive endocrine signaling. In vitro studies, mostly in animal models, have shown an inverse correlation between exposure to BPA and follicular growth, meiosis, and steroid hormone production in granulosa cells...

The relaxin family of peptide hormones and their cognate GPCRs are becoming physiologically well-characterized in the cardiovascular system and particularly in female reproductive processes. Much less is known about the physiology and pharmacology of these peptides in male reproduction, particularly as regards humans. H2-relaxin is involved in prostate function and growth, while insulin-like peptide 3 (INSL3) is a major product of the testicular Leydig cells and, in the adult, appears to modulate steroidogenesis and germ cell survival...

Gap junctions play a major role in direct, contact-dependent cell-cell communication, and they have been implicated in the regulation of cellular metabolism and the coordination of cellular functions during growth and differentiation of organs and tissues. Gap junctional channels, composed of connexin (Cx) proteins, have been detected and shown to be influenced by hormones (eg, estrogen and progesterone) in uterine and placental tissues in several species. We hypothesized that (1) the messenger RNA (mRNA) for Cx26, Cx32, Cx37, and Cx43 is expressed in the uterus of ovariectomized sheep treated with estradiol-17β (E2) and in ovine placenta during early pregnancy, (2) E2-treatment of ovariectomized ewes would cause time-specific changes in Cx26, Cx32, Cx37, and Cx43 mRNA expression (experiment 1), and (3) expression of these 4 Cx would vary across the days of early pregnancy (experiment 2) and will be affected by embryo origin (ie, after application of assisted reproductive technologies [ARTs]; experiment 3)...
